UNITED STATES PATENT OFFICE,

JEAN PIRARD, OF CHICAGO, ILLINOIS.

DETERGENT.

SPECIFICATION forming part of Letters Patent No. 645,373, dated March 13, 1900. Application filed September 29, 1899. Serial No. 732,025. No specimens-l To all whom it may concern- Be it known that I, JEAN PIRARD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Compound for Dry Cleaning, of which the following is a specification.

This invention relates to cleaning compounds'in general, and more particularly to that class employed in the process known as dry cleaning; and it has for its object to provide a compound which will be effective in removing grease and other dirt from fabrics and in which, moreover, the delicate colors and structures will not be-destoyed or injured in any way, the invention combining with certain cleaning agents which arenormally injurious certain other ingredients which, while not affecting the cleaning properties, prevent the injurious action of these desirable substances.

The compound consists of two hundred and eighty parts of benzin; Water, forty-two parts; soap, twenty-one parts; gum-arabic, fifteen parts; glycerin, thirty-six parts; ammonia, thirty parts; chloroform, twenty-five parts; sulfuric ether, thirty parts; sodium chlorid, thirty parts, and linseed-oil forty parts.

In preparing the compound the sodium chlorid is dissolved in the water at 212. The mixture is then allowed to cool, after which the gum-arabic, glycerin, ammonia, chloroform, and sulfuric ether are added,'and the compound is allowed to stand for six hours. The linseed-oil and soap are thenmixed into the'compound, and it is allowed to stand one hour, after which the benzin is added, and the material is ready for use.

I am aware thatbenzin, chloroform, sulfuric ether, and ammonia have been used for cleaning both alone and in combination with themselves and other ingredients; but the resultant compounds are too strong for delicate colors and fabrics, while the glycerin, gumarabic, and linseed-oil tone down these normally-injurious ingredients and while preserving their cleaning properties prevent them injuring the material cleaned.

What is claimed is- 1. The herein described cleaning. compound, consisting of the ingredients and the proportions as follows: benzin, two hundred and eighty parts; water, fortytwo parts; soap, twenty-one parts; gum-arabic, fifteen parts; glycerin, thirty-six parts; ammonia, thirty parts; chloroform, twenty-five parts; sulfuric ether, thirty parts; sodium chlorid, thirty parts; linseed-oil, forty parts.

2. A cleaning compound consisting of benzin, water, soap, I gum-arabic, glycerin, ammonia, chloroform, sulfuric ether, sodium chlorid, and linseed-oil.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

JEAN PIRARD.
